Hi everyone,
I recently got a problem with my Yamaha RX-V595 AV Receiver. The front display panel could stay on 3~5 seconds and then shutoff. I powered up again, it happened the same thing.
I started to check the associated DC Power Supplies and they seemed OK. (Presence of regulated voltages, +12V, -12V, +5V, B+ voltage (48V), B- voltage (48V).) Also checking on FL Display power source (Heating Element), it showed 6.7VAC on my multi-meter.
Apart from the above, I checked all Output Power Transistors (2SA1695, 2SC4688 with a multimeter ) all seemed to be OK (No short or open circuit).
Could anyone share with me in fixing the above issue? Thanks in advance.
Peter.
